Male vs Female; Not so Different?

When it comes to "male/female" thinking, I always wonder how much is biological and how much is cultural - the old "Nature vs Nurture" debate.

Scientific studies aside, I still firmly believe that women are from Venus and males are from Mars and the two species will rarely see eye to eye about anything inclusive love and spanking. And I am not saying that one species is better or worse or naturally dominant or whatever. They are simply different. And not only in humans. And, as the French love to say: "vive la différence".

From how I understood the article the study mostly showed that gender is a continuum rather than a sharp dichotomy, and most people will display traits that are stereotypically "male" or "female". However, people identifying as male will still have a higher likelihood of displaying male traits, and vice versa.

This article is also interesting in this respect:

Note that sexual behaviour is one of the areas where there do seem to be significant differences between men and women (either due to "nature", "nurture" or some interaction between the two), so this doesn't mean spanking preferences will inevitably trend towards 50/50. Most of the psychological studies debunking gender essentialism focus more on general personality and intelligence traits rather than sex preferences.
